SHUTTLE-FEELER THREAD PA TER AND CLAMP.

This invention relates toushuttle feeler thread partersand clamps for parting and clamping the filling extending from the outgoing filling carrier or bobbin towards ,the cloth selvage when replenishment of filling clamping devices whereby, when the shut? tle feeler is in its rearward shuttle feeling position, the parter and clamp may be ac tuated to part and clamp the filling and then move frontwardly to present the end of the 'filling'to the jtemplethread cutter.- "Such thread parters and clamps have sometimes been actuated to cut the filling by the front.- ward movement of the layand have been opened as the shuttle feeler ismoved rear wardly to shuttle feeling position. In some 7 other cases, also, it has-been'proposed to close the; parter and clampto perform the parting and clamping action by a train of mechanism associated withthe transferrer, and in such cases it has been usual to open the parter and clampby a separate mechanism as the shuttle feeler moves to its "rear- V tionof the transferrer.

One of the objects of'the present invena' tion is'to provide a shuttle feeler threadparter and clamp which'shall be controlled both as to its parting and opening" movements y rain of mechanism connected tothe transferrer.'-

as the shuttle feeler moves to its: rearward f position and is then yieldingly closed by the said train of mechanism in order to part 1 1 I which a pm 21 on and clamp the filling.

The invention andnovel combination of parts will best bemade clear from the fol'- lowing description and the accompanying drawings of one good form thereof.

The loom frame 1 may be of usual con-- struction and,:'as common inthis class of" looms, it has mounted thereon the hopper stand 2 for supportingthe -hopper .3in which the filling carrlers 4 are supported.- Mount-f ed on the shaft- 5 is the transfer'rer 6, the

The lay 10 carries the usual shuttle box 11 at the filling replenishing side ofthe lo'om to receive-the shuttle 12 from which the depleted filling carrier is: ejected, and a new or fresh ffilling carrier is; inserted 'on opera- These parts may be The shuttle feeler 13 is shown as pivotally mountedlat- 14 ona bracket 15 secured to the loom frame, and, in the present instance of the invention, the shuttle feeler passes .through the slotted guides-16 to directthe feelerin its backward and forward move ments. These parts also may be of. usual construction- Y Extending from the. transverse or rock shaft 17 is the arm 18h'aving a rearwardly extending portion-.19, and mounted on the arm 18 is the swinging arm 20 forming with theportion 19 of the arm 18 jaws between the shuttle feeler operates to effect movement of the shuttle feeler to and from shuttle feeling position.'

to effect certain movements of the parter and clamp as will presently appear.-

Mounted upon-the cm frame is a hear;

ing 27 in which is '1nounted tl1e=rock shaft 28, one end of which extends beyondtlie 3l of' 'which is provided with an opening 32 J into which projects a "pin 33' extending bearingas a t 29 and has securedthereon the arm 30, the rearwardl'y" extending portion from the transferrer arnr7, the effect being that upon frontward -movement of the dog 8 and the 'tr'ansferrenarm 7, as hereinbeforedescribed, the arm '30 will be actuated in a clockwise-direction" (viewing Fig. 2) to turn the rock shaft 28. r

Extending --'rearwardly from the rock shaft 28 is an arm having'an opening 35 through which extends the lower end of the rod' T-26," the upper end of which is pivoted toam; movable parter and clamp. *Below,

the 'openlng in the arm 34the rod' 26 is provided with'screw threads 36 in which'is mounted the adj ustable nut 37 and the lock; ng-nut38.= a p The rod- 36 above theopening 35' in the arm 34 is providedwith a washer or sliding collar 39 on' whichrests one end of a spring 40, the upper jend=portion of which bears against a shoulder 41 on the rod, the construction being such that should the-arm 34' be raised relative to the rod 26, the thread parter' and clampwould be actuatedyield ingly'through' the spring 40' to part "and clamp the thread;

=Rotative movement of the 'rock' shaft 28 in a c'ontrac'lockwise direction may be limited by a suitable stop, which'inthe present instance comprises the projection 42 secured in 'fixed position or formed as part of the fixed bearing 27; and upon the projection 42 the arm 34 may rest'when-the parts'are in normal position, as indicated "in Fig; 2.

and as -the: shuttle "feeler then moves frontwardly to the: position' indicated in Fig; '2,
